Market profile: electron microprobes.
Electron microprobe analysis (EMPA) is a non-destructive surface analysis technique. Electron microprobes bombard bom·bard
tr.v. bom·bard·ed, bom·bard·ing, bom·bards
1. To attack with bombs, shells, or missiles.
2. To assail persistently, as with requests. See Synonyms at attack, barrage2.
3. a small area of a sample (about 1 to 3 micrometers in diameter and depth) with focused electrons to produce x-rays, which are measured using a wavelength-dispersive (WD) or energy-dispersive (ED) spectrometer to provide quantitative and qualitative information element analysis.

WDS Wavelength Dispersive Spectroscopy is used for a more precise analysis of concentrations down to 0.01 weight percent. In addition, quantitative analyses require polished sample surfaces. EMPA can analyze all elements except for helium, hydrogen and lithium. EMPA also produces backscattered electrons, secondary electrons and cathodoluminescence Cathodoluminescence
A luminescence resulting from the bombardment of a substance with an electron (cathode-ray) beam. The principal applications of cathodoluminescence are in television, computer, radar, and oscilloscope displays. and can be used as a scanning electron microscope scan·ning electron microscope
n. Abbr. SEM
An electron microscope that forms a three-dimensional image on a cathode-ray tube by moving a beam of focused electrons across an object and reading both the electrons scattered by the object and for image analysis.

Three manufacturers participate in the market. Cameca, the dominate player, manufactures the SX100 and SX100R fully automated universal EPM EPM
equine protozoal myeloencephalitis. analyzers. JEOL's JXA-8200 can analyze as many as 21 elements, while Shimadzu's EPMA-1600 features secondary electron resolution of 6nm. Electron Microprobe Automation Systems are provided by Advanced MicroBeam, Thermo Noran and Geller MicroAnalytical Laboratory. The initial system market for EPM analyzers totaled around $20 million in 2000 with growth in the low single digits.
EMPA has applications in a variety of disciplines, including geology, archeology, materials science, metallurgy, chemistry, physics, electronics, biology, medicine, environmental science and engineering, forensics See computer forensics. , archaeological, glasses, ceramics, metals and thin films. Commercially, its most popular applications are in the semiconductor and petroleum industries.
